I'd like to ask a question but perhaps in a little bit of a different way. We've heard, through various questions asked of you, about the railways' obligations to the shippers, and I guess I'd like to ask it the other way. Does this confer any obligations on shippers to the railways? Is there something that shippers are being asked to do, notwithstanding historical challenges that have been there? I'd like to get a feel for that.
Perhaps you or your staff could help us with that.
